Gifted Versus Believing

A man may be profoundly gifted, have a strong consciousness of self, undergo deep natural-religious experiences — until he has more than these, compared to the inwardness under discussion, he remains superficial. On the other hand, the man of strictly commpnplace natural gifts has that "dimension" in him when he believes in the God of revelation and loves Him. The point is such that interiority is not psychologically deeper, or spiritually nobler, but essentially different from any natural interiority; it is a gift of grace from the Spirit.

Romano Guardini, The Conversion of Augustine

So true.
